APPARATUS FOR OPERATING ON SHEET MATERIAL This invention relates toapparatus for and process of operating upon sheet metal stock, andoperates either on flat stock which is feed or stock which is fed andshaped into any form in cross section, the stock being then cut intosections.

One object of the invention is to provide an improved apparatus of thischaracter wherein moving stock is operated upon by a tool arranged to beoperated intermittently, whereby adjacent sections of the stock betweenthe portions engaged by the tool may be of equal or non-equal length.

Another object of the invention is to construct an improved apparatus ofthis character where in moving stock is successively cut onpredetermined relatively spaced lines, whereby adjacent portions orsections defined by the cuts may be of equal or non-equal length.

Another object of the invention is to construct an improved apparatusfor severing fiat stock, or stock shaped therein, into sections ofuniform. or non-uniform length.

Another object of the invention is to construct an improved apparatus ofthis type wherein provision is made to punchor stamp a portion of thestock at uniform or non-uniform spaced points, form it intopredetermined cross sectional shape and sever the stock into sections orlengths in line with selected apertures or between any two selectedapertures. l

A further object of the invention is to provide an improved processwherein sheet metal stock of indefinite length is punched or stamped atuniform or non-uniform spaced points, and finally severed into sectionsof uniform or non-uniform length.

Another object of the invention is to construct an improved apparatus ofthis type wherein provision is rnade for readily changing the spacing ofthe apertures and/or lengths of the severed sections.

Other objects of the invention will be apparent to those skilled in theart to which my invention relates from the following description takenin connection with the accompanying drawings.

In the use of the word punching or stamping or words of like importherein I have in mind the step of slitting or up-setting the metal atand inwardly of either or both edges of the stock,

or between its edges, or blanking or notching out portions of the stockat either or both its edges or between its edges; in this connection theterm tool is intended to comprehend a device capable ofefiecting any ofthese operations. Also, since is Claims. (01. 164-45) the mechanism fora slitting, rip-setting, blanking or notching the stock, is similar tothat used for severing the stock into lengths, except for the shape ofthe tool and die, the term cutting and the like are to be interpretedina broad sense, the descriptive of rather than limiting the invention.Furthermore, in thefuse herein of the term hollow bodies I have in mindtubes or pipes wherein the side edges of the stock are related, topermit the welding thereof, and other cross sectional shapes, such assupporting. columns for buildings, sash and door frames and the like,wherein the side edgesof the stock are spaced from each other, oneexample of both forms thereof being shown in my co-pending applicationfiled July 25, 1938, Serial No. 221,126, now Letters Patent No.2,234,999, dated March 18, .1941.

In the aforesaid application I have disclosed apparatus wherein thepreliminary apertures or notches upon the stock control the punching orstamping. and severing mechanisms, whereby, the cuts or notches areuniformly spaced and the stock, when. finally severed, is formed intosec tions of uniform length. In the herein disclosed apparatusI haveprovided means which may be operated by the work or otherwise and set orarranged. to uniformly or non-uniformly space the successive aperturesupon. the stock and severing means which may beoperated by the work orotherwise and set or arranged to sever the stock inv line with, selectedapertured or intermediate the apertures to provide successive sectionsof uniform or non-uniform length.

In the drawings, l indicates as an entirety a supporting means on whicha preliminary punching mechanism, indicated as an entirety at 2, ashaping mechanism indicated as an entirety at 3 and a final cutting orsevering mechanism indicated as an entirety at 4, are mounted. Forconvenience in manufacture and assembly and adjustment of each mechanismas a unit relative to the other mechanisms, and also because eachmechanism may be associated with various types of mechanisms, thesupporting means I consists of separate supports, namely la on which themechanism 2 is mounted, lb on which the mechanism 3 is mounted and lo onwhich the mechanism 4 is mounted. The support la is provided with spacedstandards 5 having suitable bearings to support a shaft 5a, carrying acam 5b to which reference will later be made. At one end the shaft 5arotatably mounts a flywhee1.5' which is continuously driven by a belt 5afrom a pulley ii on the shaft of a motor to. Between the flywheel 5 andshaft 5a is a suitable clutch for connecting the shaft to the flywheel,so that by means of control elements (later referred to) the shaft isdriven and stopped at the end of one revolution thereof, the effect ofwhich is to operate the preliminary stock engaging tool, a down strokeand an up-stroke thereof; a friction member la (see Fig. 2) bearing uponthe opposite end of the shaft 5a serves to stop its rotation after itsrelease from the driven element of the clutch. As later set forth, thepunch and its co-acting die or wall serve to punch the stock atpredetermined spaced positions, as determined by the control elements,such aperture making in the illustrated example consisting of centrallydisposed openings (1 (see Fig.

10) spaced longitudinally of the stock, each opening being formed by thedown stroke of the tool. 5 The standards 5 are provided with upwardlydisposed hollow extensions 1 forming guides for slidable rods 8 carryingat their upper ends a cross head 9 and rigidly connected at their lowerends to a yoke it the sides of which are formed with elongated openingsto accommodate the shaft 5a and permit the yoke to reciprocate up anddown.

The lower end of the yoke H3 is provided with a depending pin H, whichextends through and is guided by the walls of a bushed collar l2 suit- 1ably seated in the top wall of the support or base la. Between theflange of the collar !2 and lower end of the yoke It and surrounding thepin H is an expansion spring 13, which normally tends to bias the yokeiii upwardly and through it to move the cross head a upwardly. Withinand adjacent the lower end of the yoke I6 I mount a shaft it on which isloosely mounted a roller 1a in engagement with the cam 5b, the throw ofwhich serves to move the yoke l3 and cross head downwardly in oppositionto the spring it. The cross head 9 is provided with a depending block itbetween which and a plate l'i provided on the upper ends of thestandards 5, are slidably mounted the die and support for a. thepreliminary tool. At its forward end the plate IT is provided withbrackets l8 to the outer ends of which springs i9 are anchored at oneend, their opposite ends being connected to the die block or support forthe die which co-acts with the tool and normally tend to move it and thetool rearwardly against a stop 29, so that when the die and tool moveforwardly with the material A and are disengaged therefrom, as later setforth, they will be automatically returned to their normal positionagainst the stop 29. At its rear end the plate H is provided with abracket Ha which and a bracket 2a on the base to support a table 2! overwhich the material A moves in feeding from the preliminary punchingmechanism 2 to the shaping mechanism 3, the

table 2! having a length to provide for maximum adjustment of theelement, which is mounted adjacent thereto, relative to the tool andcontrols the operation of the clutch to effect operation of the tool.

-On their front sides, the standards 5 are provided with suitablebrackets 51), which support at their upper ends a freely rotatableroller over which the stock is fed to the die.

The die preferably consists of a sectional block 22 providing an openingthrough which the stock feeds and walls which co-act with the tool 23(see Fig.3) obviously more than one tool may be provided dependent uponthe resulting product to be produced. The die block is mounted on aslide 23 which is provided on its opposite lower sides with inwardlyextending strips arranged to engage ways or guides on the plate I! toreciprocatably mount the block on the latter; whereas the tool 23 isfixed to a slide 25 which is provided on its opposite upper sides withinwardly extendin strips arranged to engage ways or guides on thedepending block it to reciprocatably mount the tool on the latter. Theslides 26 and 25 are connected together for reciprocation as a unitbetween the plate ll and head 9 by pilot pins 26, preferably mounted inthe die block 22 and telescopically fitting sleeves 26a supported in anddepending from the slide 25, as shown in Fig. 3. The mounting of the dieand tool as above debribed per-mits them to move forwardly with thestock or work during "operation thereon independently of the down and upstroke of the tool and also in a dvance of the down stroke of the tool,since the control elements (later referred to) for releasing the onerevolution clutch are connected to and operate through the die block todrivingly connect the clutch to the shaft M, as later set forth.

The stock A is fed or moved relative to the operation performingmechanism 2 by the shaping mechanism 3, the rolls of which are driven.The mechanism 3 consists of a plurality of sets of rolls 3a suitablymounted in housings 5b, the number of sets of rolls 3a being dependentupon the cross sectional shape to be imparted to the stock and thicknessthereof, as well as other conditions. The shafts for the shaping rollsof each set are geared together and drivingly connected to a shaft 21,such gearing and connections being mounted in casings Zia and the shaft2! being driven through a suitable clutch 28 by a power means indicatedat 29 (Figs. 1 and 2) deriving its power from a motor (not shown) withinthe support lb. The clutch Z8 is operated by the linkage 39 supported inposition to be grasped by the 0perative. The shaping rolls 3a hereinshown for illustrative purposes are arranged to progressively bend thelateral portions of the stock (see dotted lines in Fig. 13) to form achannel A, as

shown in full lines (Figs. 10, ll, 12 and 13). As shown in Figs. 1a and2c, the sets of driven rolls 3a are utilized to feed the stock, that is,to draw it from a coil or other source of supply and feed it through thedie '22 of the operation performing mechanism 2; but if desired themechanism 3 may include a set of pinch rolls in front of the first setof shaping rolls.

The elements or means for controlling the operation of the cross head 9are indicated as an entirety at 3! and comprise the following: 32indicates a shaft'rnounted in a standard 32, which is a'djustably fixedto the support ib. That end of the shaft 532 remote from the stocksupport or table i provided with a sprocket 33 engaged by a chain 33a,the latter being driven by a sprocket 3:2 to the extended end of thelower shaft for the first set of rolls 3a of the mechanism 3. The otherend of the shaft 32 is provided with a tool locating or metering member35 consisting of a disk provided with one or more lugs or projections,each arranged to r leasably engage with a dog 33. By preference, thelugs 35a are disposed in an annular series on the outer face of the diskand spaced relatively to each other in any predetermined manner so as tooperate the dog 35 as each passes the latter. The lugs are removablymounted on the disk, each consisting of a screw loosely supporting aroller and threaded at its inner end into an opening 351) formed in thedisk. The openings 35b in the disk 35 are preferably uniformly spacedtherearound to provide for the maximum number of operations of the dogto, each of winch effects operation of the cross head 9 as the disk 35rotates, but by removing certain of the lugs, the number of operationsof the dog 36 may be reduced, whereby the angular movement of the disk35 between each lug and the succeeding lug may be increased or decreaseddependent upon the space between adjacent openings or multiples thereof,such spacing between adjacent lugs determining the. spacingcf theopenings a in the stock It will be understood that the disk 35 isremovable from the shaft 32 so that a disk with lugs 35a mounted thereonin any predetermined order maybe substituted to avoid changing the lugson the disk. The dog 35 is pivoted to a rod 3?, which is connected atits inner end through a plate 33a to the die block 22, so that when thedog 36 is engaged by each of the lugs 35a and moved forward thereby, thedie block 22 is moved relative to the plate H in opposition to thesprings 19, and the shaft 5a is connected to the one revolution clutchas later set forth. The dcgfit is pivoted to a supporting evice 33 whichis adjustably fixed to the rod 37 to position the nose Elia of the dogin a predetermined relation to the lugs 35:; as they approach and recedefrom their uppermost position. The rod 3? is slidably supported on aplurality of brackets 35 suitably fixed to the work support 2 l. Theopposite ends of a contractile spring ii) are fixed to the outermostbracket 39 and a head it-a, on the outer end of the rod 3?, this springbeing put under tension when the rod 31 is moved endwise (toward theleft as viewed in Figs. 1a, 5, 6 and 7) by the dog to supplement theaction of the springs l? in returning the die, rod and dog to normalposition after each punching operation. The dog is provided with a leafspring 39, the free end portion of which engages the rod 3? and normallytends to swing the dog downwardly, which movement of the dog is limitedby the engagement of its tail portion 3% with the lower side of thedevice iii Each lug 35a in its movement counter-clockwise (see Fig. 6)engages with and moves the dog 35 a predetermined distance andautomatically disengages therefrom as the lug 35a continues in its pathof movement. The nose may be shaped to permit its ready disengagementfrom each lug, but preferably the nose 35a is slightly recessed andmeans are provided for positively moving the nose 35a out of the path ofmovement of each lug at a predetermined position, these means consistingof related inclines or cams 52a, 52, provided respectively on the outerend of the dog to and the front end of a plate 42b secured by screws 52cthe side wall of the work support 21.

As will be understood from Figs. 6 and 7, the engagement of the cam 42awith the cam 42 in the forward movement of the dog serves toswing thelatter upwardly and thus effect the disengagement of the dogs nose 36afrom each lug. Accordingly, these means (i) may be arranged to releasethe dog from each lug in advance of the release which would otherwiseoccur due to the path in which the lugs travel and (2), provide for theoperation of the dog 36 and movement of the die therewith to effectactuation of the tool 23, as later set forth. As shown in Fig. 6, theside wall of the table 25 is formed with elongated slots through whichthe screws 42c extend, the slots permitting the plate 422) to beadjusted to accurately relate the cam 32 on its front end to the cam 42aon the dog to effect the positive release of the latter from each lug atthe desired time.

As the dog 3% is connected to the rod til, the latter moves the die andtool therewith and such movement effects operation of the clutch torotate the shaft 5a and reciprocate the tool by means of the followingdevices; 43 indicates a pair of spaced arms fixed to the brackets l8 andprovided adjacent their outer ends with inclined walls 43a. M indicatesa release member pivotally connected at its inner end to the slide 24and disposed between the arms 43 and carrying at its outer end laterallyprojecting pins 45 normally disposed rearward of the inclined walls 43aand arranged to engage therewith in the forward movement of the slide,whereby the walls 43a serve to swing the release member upwardly as itmoves forwardly with the slide 24. On its lower side, the release member44 is provided with a shoulder 44a arranged to engage and swing a lever46 suitably fulcrummed on a depending bracket iiia, when the slide ismoved forwardly, as already set forth, the release member 44 thendisengaging the lever 45 by reason of the engagement of the pins 45 withthe inclined walls 43a, which swing the release member upwardly, as justset forth. The walls 43a ermit the release member 44 to swing downwardlyinto operative position, with the shoulder 44a behind the lever 46, whenthe slide 24 is returned or moved rearwardly by the springs E9. Theother end of the lever 46 is pivoted to one end of an arm and theopposite end of the arm t? is pivot-ally connected to one endof a tripdevice '28, mounted to rock on a stud shaft 6-9. The trip device 68 isformed with a recess iii in which is siidably mounted a plunger Eda, anexpansion spring 52 being interposed between the inner end of theplunger and the bottom of the recess and normally tending to project theplunger outwardly. As shown, the plunger 56a is disposed in engagementwith a stationary pin or abutment 53, so that the expansion of thespring serves to swing the device 48 about the shaft 49,counter-clockwise as Viewed in Fig. '7, such movement being limited bythe engagement of a projection 54 on the device 48 with the abutment 53,as shown. The counter-clockwise movement of the trip device 43, throughthe arm 41, serves to return the lever 46 to its normal position, whichis predetermined by reason of the engagement of the projection 54 withthe abutment 53, so as to be operatively related to the shoulder Ma whenthe release member is returned to its rearmost or normal position. Thetrip device 58 is provided with a shoulder 55, which-when the lever 4'5,arm M and trip device are in their normal positions as shown in Figs. 1aand 7lies in the path of movement of the dog 56 on a collar 56a. Thecollar 56a is connected to that element of the one revolution clutch 56bwhich controls the connection with and disconnection of the clutch fromthe shaft 5a. As the clutch is of well known construction, it is notillustrated in detail. As will be understood, when the dog 56 is inengagement with the shoulder 55, the clutch is ineffective anddisconnected from the shaft 5a, but upon movement of the shoulder 55 tothe position shown in dotted lines in Fig. '7, due to operation of thelever 46, the collar 55a will be released and thus effect operation ofthe clutch to rotate the shaft 5a.. As the lever 46 is released from theshoulder Ma of the release member 44 in co-ordinated relation to andimmediately following the disengagement of the shoulder 55 from the dog56, and is then returned to its normal or predetermined position underthe influence of the spring 52, it will be 6 seen that the shoulder 55is re-positioned in the path of movement of the dog 56 to arrestrotation of the collar 56a at the end of one revolution thereof, so thatthe clutch is released from the shaft 5a when the latter has made onerevolution. The shoulder 55 is preferably mounted on a plunger til whichslidably fits a recess formed in the walls of the device 38, anexpansion spring being interposed between the inner end of the plunger51 and the bottom ofthe recess and normally tending to slide the plungeroutwardly, this arrangement serving as a cushion to absorb the blowincident to the engagement of the dog 56 with the shoulder 55. Theplunger 51 is provided with a pin which slides in a slot formed in thewalls of the device 48, the end walls of the slot serving to limit themovement of the plunger 51 in either direction.

58 indicates a guide for the stock A mounted on the support 2 I It willbe understood that the mechanism 2 may be operated independently of anyother mechanisms, for example, upon stock previously cut into lengths;also where shaping of the stock is not required, it may be combined witha cutoff or severing mechanism such as shown at 4. In these referred toexamples, the stock may be previously shaped, in which event the openingthrough the die block is shaped in cross section to accommodate theshape of the stock. In these referred to examples, the tool locatingmember may be drivingly connected to the motor 6a or otherwise driven.

It will also be noted that the driving means between the shaft 32 andshaping roll shaft may be of any desired construction and that the speedof the shaft 32 relative to the roll shaft may be of any desired ratioto provide a predetermined relation between the rotary movement of thedisk 35 and feed of the stock A so that the successive operations of thedog 36 by the lugs 35a will effect the operation of the tool to properlyspace the openings a.

Figs. l4, 15, 16, 17 and 18 illustrate modified forms of tool locatingor metering devices. As shown in Figs. 14 and 15, the device consists ofa disk 35x formed with a plurality of arcuate slots 35m in end to endrelation and concentric to the disk axis and the shanks of the lugs 35aextend through the slots and are secured thereto by nuts 35, the slotspermitting the lugs to be adjusted relatively to each other. The deviceshown in Figs. l6, l7 and 18 is later referred to.

The stock may be severed into sections by any suitable cut-off orsevering mechanism 4, but preferably by a mechanism employing a tool 10-eat ng or metering device so that the severing of the stock may be ontransverse lines through or between the openings and uniformly ornonunifcrmly spaced, whereby the sections may be of equal length, orcertain thereof may differ in length from an adjacent section. In orderto obtain these advantageous results, I have shown a severing mechanism6, which is similar in construction and operation to the mechanism 2,the tool locating or metering device being indicated at 59 and driven bya chain 60 from the shaft for the lower roll of the last set of rolls 3aof the mechanism 3, thereby synchronizing the operation of the cuttingelement 6! (see Fig. 4) with the rate of feed of the shaped stock A.

In the arrangement shown, the tool locating device as is provided withtwodiametrically arranged lugs 35a, so that in each revolution of thisdevice the stock A is cut into two sections of equal length, but bychanging the angular relation of one lug relative to the other lug, onesevered section would be longer than the other section.

It will be understood that since the mechanism t is similar inconstruction and operation to the mechanism 2 it is not illustrated indetail and further description thereof appears to be unnecessary. Itwill also be understood that my invention is not limited to acombination wherein the mechanism between-the mechanism 2 and 4 isconstructed to shape the material A, but other mechanisms maybe'employed, for example, a mechanism for slitting, trimming or levelingthe stock. Where such a mechanism is omitted, the tool locating member58 for the severing mechanism may be driven by a suitable motor. In thearrangement shown, the speed of th lugs on each tool locating memberapproximates the speed of the stock, so that the die and cutter aremoved with the stock by each lug until the dog 36 is released therefrom.

It will thus be noted that the tool locating member and the operatingconnections between it and the release means for the clutch 53b servethe dual function of operating the release means and moving the die andcutter with the stock during the cutting operation, until the dog 36 isreleased, but where other means are enployecl for effecting this fixedrelation between the stock die and cutter (for example, as shown inLetters Patent No. 2,155,396 to Alexander Borzym) the operatingconnections may be directly related to the release means. However, I mayprovide between each tool locating member and its driving means,suitable means Eli for regulating the speed of the tool locating memberso that the speed of the lugs in their orbit will be faster or slowerthan the speed of the stock to provide a predetermined spacing of thecutting or length of the severed sections; this difierential speedrelation may be provided since the die and cutter beingfree to slide onthe plate I7 and block it, they will move with the stock duringengagement of the cutter therewith.

It will be noted however, that in all speed relations between the toollocating or metering lugs 35a and stock, the cam 42 must be so set thatrelease of the dog 3% from each lug takes place simultaneously with orfollowing the engagement of the cutter with the stock, to preventrearward movement of the die and cutter (prior to such engagement) underthe influence of the adjacent springs [9.

Referring to Figs. 16 to 29, inclusive, t2 indicates a tool locating ormetering device keyed to a shaft 62a, which is suitably mounted in therame is. The tool locating or metering device is provided with one ormore operating lugs [33, .pre-deterrninedly spaced for the purposes asalready set forth and each arranged to engage and move the dog which inturn moves the rod 37 to operate the release means as already describedin connection with Figs. 1 to 13, inclusive. The tool locating ormetering device is driven through a train of changeable gears by a roll64 which engages with and is rotated by the moving stock A on the tableH. The roll 64 is r movably fixed to one end of a shaft 65, which ismounted in suitable bearings provided in the ou er end of an arm 6511,the inner end of the arm being pivoted on a shaft 85 suitably mounted onthe frame la, whereby the arm 65a may be operated about the shaft toinsure adequate engagemcnt of the roll 34 under pressure with the stock,to effect positioning of the stock on the table 23 or to permit readyremoval of the roll 64 where a roll of a different diameter is required.The shaft 55 is provided with a gear 6'! in mesh with a gear fila keyedto the shaft 63. The shaft (it is provided with a second gear 68 in meshwith a gear 69 fixed to a shaft tfia, which is suitably mounted in theframe la. The shaft 69a is provided with a second gear T8 in mesh with agear a. fixed to the shaft 62a. As above Set forth the roll 64 and gearsare removable, whereby any desired-speed of the tool locating device 62may be provided for. By preference I provide a backing roll H below andin engagement with the moving stock, in alinement with the roll 64, sothat when the latter is positioned under pressure, as later set forth,the roll 64 will be rotated by the stock without danger of slippage; thetable 2| being formed with an opening Zlx t perrnit the roll H to engagethe moving stock. The backing roll H is freely rotatable onanti-friction hearings on a shaft ll preferably secured to the side wallof the table 2|. For the, purpose of positioning the roll as inengagement with and under pressure against the stock, I provide on theframe is a bracket M which is formed with a threaded opening to receivean externally threaded collar iii. The collar 13 is internally threadedto receive and support an externally threaded, hollow member M forming aguide for a thrust device or plunger Ma. The upper end of the plunger Mais provided with a transver ely disposed pin the opposite ends of whichextend through elongated slots formed in a pair of spaced plates 75 andconnects the plunger thereto. The upper portions of the plates 16 areconnected to the opposite ends of a shaft its on which the inner end ofa lever ll swings, the outer end of the lever terminating in a suitablehandle. The inner end of the lever H is shaped to provide on itsperiphery a cam Ila the high spot of which is arranged to engage theupper end of the plunger Ma and force it downwardly when the lever I? isswung to the position shown in Figs. 16, 17 and 18, the high spot of thecam being related to the axis on which the lever ll swings to lock thelever in operated position. A screw 18 adiustably mounted in a lug 18a,provided on the lever Ti and arranged to engage one of the plates 76serves to limit the movement of the lever so as to prevent movement ofthe high spot of the cam to a point where the plunger would be relieved.The opposite ends of the pin 15 pivotally support a pair of links 18formed with elongated slots 19a throughout their outer end portions. Theslots 19a receive pins til projecting laterally from the opposite sidesof the lever Tl, the pins 83 and links 7% serving to connect the plungerits to the lever so that when the lever is swung upwardly following therelease of the cam from the plunger, the latter will be lifted. A coiledspring 3! is interposed between the lower end of the plunger 14a and thearm a so that the roll 65 may accommodate itself to slight variations inthe thickness of the stock and maintain uniform pressure thereon. Theupper end of the spring 8! fits into an annular recess formed on thelower end portion of the plunger Ma to connect the spring thereto, sothat when the plunger is raised, pressure of the roll 64 on the stock isrelieved.

In these views I have shown a modified form of tool locating device 82which may be employed in the form of construction shown in Figs. 1 to 13or the forms hereinafter referred to. The device 62 consists of a mainsection 822) and a removable annular secticn 6% having on their opposedfaces annular recesses 620 related to form a continuous slot in whichthe lugs 63 are adjustably and removably mounted, The section 6217' is rmovably secured to the section 62b by bolts 626. As shown in Figs. 19and 20, each lug 63 consists of a body portion 63a formed with a throughopening 63 and having depending side members 83?), the outer walls ofwhich are inclined downwardly and outwardly to fit correspondinglyshaped walls of the recesses E26. The upper end of the body portion 63ais provided with a laterally extending wall fitd for engagement with thenose of the dog 36 as shown in Fig. 18. The lugs 653 may be secured inposition by the annular section 62b, but to permit independentadjustment of the lugs I taper the inner side walls of the members 631)and insert therebetween a tapered pin Me which operates to spread themembers 632) into clamping engagement with walls of the recesses 62 Theupper end of the opening 63a is enlarged and threaded for engagement bythe externally threaded head of the pin 36, so that when the latter isrotated its tapered shank is forced downwardly to spread the sidemembers 63b.

Referring to Figs. 21 to 24, inclusive, 82 indicates the tool locatingdevice provided with lugs 82a each arranged to engage and operate thepawl 36, which in turn moves the rod 31 endwise to eifect operation ofthe release means, indicated as an entirety at 53. The release means 33control the locking and release of a shaft 8 3, which is initiallyrotated by springs (one being shown at tea) and power driven to completeits rotation and re-set the springs, for example, as set forth in theaforesaid Letters Patent No. 2,155,396, the rotation of the shaftserving to reciprocate the cross head (not shown) which carries thetool. In this arrangement, the shaft 85 is provided with a disk 35having on its periphery a lug 85a arranged to engage a release device 85carried by one arm 8'? of a lever 83. The lever $8 is fulcrumed on ashaft 39 and normally biased (counter-clockwise as viewed in Fig. 22) tothe position shown in Fig. 22 by a coiled spring (see Fig. 24) against astop Sii. Another arm Sl'a of the lever 88 is arranged to engage ashoulder on a trip device 9i (as shown in dotted lines in Fig. 21). Thetrip device 9i is fixed to one end of a rock shaft 92, which is normallybiased (counter-clockwise as viewed in Figs. 21 and 22) against a stop92a and carries at its other end an arm 93. The outer end of the arm 93is arranged to be engaged by a shoulder Q3 provided on the adjacent endof the rod 37, so that when the rod is moved endwise by each of the lugs82a on the tool locating member, the

arm 93 is swung to the position shown in Fig. 22

to rock the shaft which in turn swings the trip device at upwardly torelease the ever $3. The lever $8 is operated under the influence of thespring 8% to release the lug 85a, whereby the springs S lo start therotation of the shaft 84.

As the lug 85a approaches its starting position it engages the cam 81?)on the lever arm 87c and swings the lever 83 clockwise to move therelease device 86 into the path of movement of the lug a and to positionthe lever arm 87a behind the shoulder on the trip device 8!, which holdsthe lever against counter-clockwise movement and permits the releasedevice 86 to stop the shaft or upon engagement of the lug 35a therewith.The rod 3'5 is returned to normal position by spring 9 5a interposedbetween an abutment 94b and a collar 9 0 fixed to the rod 31. Theshoulder 94 is provided on a fitting 9 through which the rod 31 extendsthe rod being threaded to take nuts 95 between and by means of which thefitting may be adjustably secured to the rod. The outer end of the arm93 is provided with a pivoted dog 93a which is locked against movementin one direction so that the shoulder 94 may transmit its movementthrough the dog to the arm 93, but is free to swing in the oppositedirection so as to permit it to swing in opposition to a spring 9322 andride the shoulder 94 in the return movement of the latter.

The tool locating device 82 may be driven in the manner shown in Figs. 1to 13, inclusive or as shown in Figs. 16, 17 and 18.

Fig. 25 illustrates a further modified form of cutting mechanism whereinthe tool locating member 62a: is provided with operating lugs 633:, eacharranged to operate a normally open snap switch mounted in a casing 95,as the tool locating device rotates, to close a circuit 95', in which isconnected the coil of a solenoid 85a. The tool locating member 62a: isdriven by a roll 91 engaging the moving stock A in opposed relation to abacking roll 91a. The roll 91 drives the tool locating device through atrain of change gears (not shown) as shown in Figs. 16, 1'7 and 18. Thecutting mechanism shown is similar to each of the mechanisms 2 and t,except that the trip device 43, which releases the collar 56a to eifectthe connection of the one revolution clutch to the shaft 5a andre-engages the collar to disconnect the clutch from the shaft iscontrolled by the solenoid 96a. The snap switch may be of any desiredconstruction. The movable element of the switch is provided with an arm2%, the outer end of wlL'ch is arranged to be engaged by the lugs 63:0.The arm 8% is extended rearwardly and provided with spaced upper andlower lugs 9E0, Site, which straddle a stop 96w suitably fixed to thecasing 96. An expansion spring Beer is interposed between the stop 95mand upper lug 96c and normally tends to bias the arm llfibcounter-clockwise as viewed in Fig. 25 and thus maintain the switch inopen position with the lug 96c against the stop 953:, the latter servingto limit the swinging movement of the arm under the influence of thespring 9233: to position the outer end of the arm 9% in a predeterminedrelation to the path of movement of the operating lugs 53a. The outerend of the arm is preferably provided with a roller with which the lug63m engages. The solenoid may also be of any desired construction, theouter end of its core being provided with a head 88 which is pivoted tothe upper end of the trip device 48. A spring 99 is coiled around thesolenoid core between the head $3 and adjacent end of the coil support,the spring normally tending to swing the trip device 43counter-clockwise, as viewed in Fig. 25, against the stop 53, toposition the shoulder 55 on the plunger El in the path of movement ofthe dog 55 on the collar 55a. In operation, each operating lug 63xoperates the switch to close the circuit 95' and energize the coil ofthe solenoid, the effect of which is to move the solenoid core endwisein opposition -to the tension of the spring and swing the trip deviceclockwise, whereby the collar Efia is released. As the solenoid coil isenergized momentarily, its core is immediately released for movement inthe opposite direction by the spring, whereby the shoulder 55 isre-positioned for engagement by the dog his to stop the collar 53a. Thecircuit 96 is supplied with current from mains 95a upon the closing of amain switch Hit. The tool locating member 629: and the mounting of theoperating lugs 63:1: thereon are similar to like parts shownin Figs. 16,18, 19 and 20.

Fig. 26 illustrates a further modified form sim ilar to that shown inFig. 25 except that the tool locating device, indicated at Hill isdriven by a chain H32 from a source of power, for example,

the roll shaft of a shaping mechanism as shown in Figs. 1 to 13,inclusive. In this form of construction, the operating lugs Etta areremovably mounted as shown in Fig. 8. In the forms of construction shownin Figs. 25 and 26, the switch 96 may be located at any desired positionabout the axis of the tool locating device and the operating lugs may bepositioned in closer relation as compared to their spacing where thelugs engage and operate a pawl.

It will be noted that I have shown in Figs. 16

to 26 several modified forms of mechanism, each of which may beadaptedto eflect a preliminary punching of the stock or severin thereofinto sections.
